    GPIF II Master & Slave Transform Problem (M to S Pass But S to M Fail!)

    andykung6_1652411

      Hi~ A few months ago I bought two CYUSB3KIT-003 Cypress Development Kits.

         

      I try to learn GPIFII transmission function and try run Designing a GPIF™ II Master Interface example(application note: AN87216)

         

      FX3 Back-to-Back Setup Using CYUSB3KIT-003 like  AN87216 Figure 26.

         

      I test Master transform data to Slave was Pass (FX3 Firmware Master = Autoslave.img   Slave = AutoSlave.img) 

         

      For example, Master-side transfer data 0x64 0x65 0x66 0x67 0x68 0x69 0x6A 0x6B total of 8 Bytes to Slave.

         

      Slave-side Receives the correct data from Master.

         

      But test Slave transform data transform data to Master was Fail.

         

      For example, Slave-side transfer data 0x64 0x65 0x66 0x67 0x68 0x69 0x6A 0x6B total of 8 Bytes to Master.

         

      But Master-side Receives the error data from Slave. And can not be expected.

         

      What can I do for next step??
